Thanks for joining the conversation, plainjanea!

So that the Community can help you better, we need to know exactly which Canon printer model you're using within the PIXMA TS6400 series. The model number should be on the front of the unit at the lower right. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.

Thanks and have a great day!

If you just replaced the printer cartridges, make sure all the contact protection tape is removed, and then reseat the cartridges. You may need to power down the printer and restart it after a minute. Just curious did you replace the color cartridge as well?
